No unique canonical full name; this term conflates two broad classes: "Tissue surface protein" (category; e.g., "Integrin beta-1") and "Microbial cell wall" (not a protein).

The phrase "Tissue surface proteins and microbial cell wall" is non-specific and encompasses two fundamentally different entities. Tissue surface proteins are cell membrane-associated proteins in animals, including receptors and adhesion molecules mediating cell signaling, attachment, immunity, and tissue organization. Microbial cell walls are the outer structural layers in bacteria, archaea, fungi, and plants, comprising molecules such as peptidoglycan, lipopolysaccharides, and S-layer proteins, that provide structural integrity and protection, and serve as key virulence factors in pathogens. Each class is targeted differently in therapeutics: host surface proteins often by biologics or small molecules, and microbial cell wall components predominantly by antibiotics.

For tissue surface proteins, mechanisms include blockade of ligand binding, inhibition or stimulation of signal transduction, and interference with cell migration. For microbial cell walls, mechanisms involve inhibition of peptidoglycan or cell wall biosynthesis, disruption of cell wall integrity, and impairing cell division.
